Title: Shutter for photographic cameras
IPC: G03B7/083
Filed: 1967-06-15
Abstract: Electronic shutters and shutter-diaphragms comprise opening and closing blade systems which respectively uncover and cover the lens aperture, each system having two pivoted blades which are held in the cocked position by an associated electromagnetically actuated catch the blades bearing on opposite sides of the catch, and the exposure time being determined by the delay in the actuation of the catch retaining the closing blade in the cocked position. The closing and opening blade systems 3 and 4 may each comprise a pair of blades 3a, 3b and 4a, 4b pivoted at 5 and 7 respectively for movement into and out of alignment with aperture 2. Exposure is effected by manually rotating anti-clockwise a ring 40 by an arm 41, first closing a switch 51 which completes a circuit to indicate if sufficient light is available, and then closes a double-throw switch 52 which completes a flash-circuit and energizes an electromagnet 15 which attracts a plate 10b of, and hence pivots, a catch in the form of a lever 10 having a nose 10a holding opening blade 4a, 4b in the cocked position, whereby the nose is moved out of engagement with the blades which run-down under the action of springs 8 to uncover the aperture 2 to initiate exposure. After a time governed by a photo-resistor (56) a Schmitt trigger (55) energizes an electromagnet 14 which causes a nose 9a of a lever 9, similar to lever 10, to be moved out of engagement with closing blades 3a, 3b which are released to terminate exposure. Noses 9a and 10a are positioned in slots 39 in a plate 38 and are prevented from moving until the latter has been rotated by ring 40. The shutter is cocked by rotating clockwise a ring 30 by an arm 30a ring 30 has pins 33, 34 which engage and pivot cams 24, 25 respectively, having slots 22a, 22b and 23a, 23b respectively, each engaging a pin on one arm of a corresponding lever 18a, 18b, 19a, 19b respectively, the other arm of which each has a pin 20a, 20b, 21a, 21b which engages a blade 3a, 3b, 4a, 4b respectively, whereby the blades are moved into the cocked position and held by noses 9a, 10a which are returned by springs 13 or cams 60 on plate 38. The aperture defined by the opening blades 4a 4b in the open position may be set by a rotating diaphragm ring 36 having a cammed surface 37 which engages pin 34 to adjust, via cam 25, the amount of movement of levers 19a, 19b and hence of blades 4a, 4b.

Patent ES-405572-A1 (ES)
Title: Photoelectric keyboard for data input devices or the like
IPC: H03K17/969
Filed: 1972-08-05
Abstract: A photoelectric keyboard in which operation is achieved by insertion of a shutter in the light path between a source and a photocell in response to operation of a key. The shutter has pedetermined light transmissivity. Operation of a second key before the first is released inserts a second shutter in the light path and reduces the received light level below a predetermined threshold at the photocell so that ambiguous code generation does not occur during key overlap. So-called "key locks" are, therefore, unnecessary and individual styles of writing, including the "Legato-Writing", are not inhibited.
